Foreword

YS/T 53 "Copper, lead, zinc ore tailings and chemical analysis method" is divided into three parts. --- Part 1. Determination of the amount of gold fire assay enrichment - flame atomic absorption spectrometry; --- Part 2. determination of gold by Flow Injection Micro - column separation -8531 fiber enrichment - flame atomic absorption spectrometry; --- Part 3. Determination of the amount of silver by flame atomic absorption spectrometry. This is Part 1. This section is in accordance with GB/T 1.1-2009 given rules drafted. The partial replacement of YS/T 53.1-1992, this portion of YS/T 53.1-1992 compared to the main changes are as follows. --- Deleted TMK spectrophotometry; --- Measured by the scope of 0.001g/t ~ 1.0g/t adjusted to 0.05g/t ~ 3.0g/t; --- Omitted "reference standard" one; --- Text format has been modified; --- Complements the precision, quality assurance and control provisions. The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized. This section is drafted. Shuikoushan Hunan Nonferrous Metals Group Co., Ltd., Guangzhou Nonferrous Metal Research Institute, Beijing Mining and Metallurgy Research General Hospital.
